This is kinda ugly, but works for protection:

It peels off. I used clear PlastiDip. Bought it on fleBay.
I put an old broken atty on it and dipped the bottom a little past the joint where it screws to the top. I clamped it by the atty with a pair of vice-grips and let it hang over the edge of the workbench with the atty facing up. This let the excess run down and drip off the bottom. After about 10-12 minutes it had gelled a little. I turned it over so the atty was facing down. This let the bottom flatten out as it dried. I made two dips like this. Let it dry for at least 24 hours.
I began rolling the edge back towards the bottom. All the way to the bottom, then remove it. I won't say what it looks like...
I then dipped the bottom again as before and after dry, trimmed with a razor blade.
Take the atty off and roll the first dip back over the top piece. Take a small razor knife and cut a hole for the atty connector. Cut an edge with a razor blade along the joint where the top and bottom screw together.
I've discovered that they shrink a little in length after being removed and put back on. But still work great for protection.
I'm going to try again, but maybe play with some color this time.
